Fossil discovery solves mystery of how pandas became vegetarian

Sat, July 2, 2022 


The discovery of panda fossils in China has helped researchers solve the mystery of how the giant species developed a "false thumb" and became the only dedicated vegetarian in the bear family.

Fossils dating back about six million years found in southwest China's Yunnan province included a greatly enlarged wrist bone called a radial sesamoid.

It is the oldest known evidence of the modern giant panda's false thumb that allows it to grip and break heavy bamboo stems, scientists wrote on a research paper published in the latest edition of the Scientific Reports.

The fossils belong to the now-extinct ancient relative of the panda called an Ailurarcto that lived in China six to eight million years ago.


"The giant panda is... a rare case of a large carnivore with a short, carnivorous digestive tract... that has become a dedicated herbivore," Wang Xiaoming, curator of vertebrate palaeontology at the Natural History Museum of Los Angeles County, said.

"The false thumb in Ailurarctos shows... for the first time, the likely timing and steps in the evolution of bamboo feeding in pandas."

Researchers had known about the panda's false thumb, which works similar to a human thumb, for about a century. But the lack of fossil evidence had left unanswered questions about how and when the extra digit -- not seen in any other bear -- evolved.

"While the giant panda's false thumb is not the most elegant or dexterous... even a small, protruding lump at the wrist can be a modest help in preventing bamboo from slipping off bent fingers," Wang wrote.

The fossils found near Zhaotong city in the north of Yunnan included a false thumb that was longer than that found in modern pandas, but without an inward hook on the end.

The hook and a fleshy pad around the based of the thumb evolved over time since it had to "bear the burden of considerable body weight", the paper said.

Pandas traded the high-protein, omnivorous diet of their ancestors for bamboo, that is low in nutrients available year-round in South China millions of years ago.

They eat for up to 15 hours a day and an adult panda can consume 45kg of bamboo a day. While their diet is mostly vegetarian, wild panda are known to occasionally hunt small animals.

'Fragile situation' in Libya as anger seethes over living conditions

Libya’s rival leaders were under growing street pressure Saturday after protesters stormed parliament as anger exploded over deteriorating living conditions and political deadlock.

Libyans, many impoverished after a decade of turmoil and sweltering in the soaring summer heat, have been enduring fuel shortages and power cuts of up to 18 hours a day, even as their country sits atop Africa’s largest proven oil reserves.

The country has been mired in chaos and repeated rounds of conflict since a NATO-backed uprising toppled and killed dictator Moamer Kadhafi in 2011.

Protesters stormed the seat of the House of Representatives in the eastern city of Tobruk on Friday night, ransacking its offices and torching part of the building.

In both the main eastern city of Benghazi—the cradle of the 2011 uprising—and the capital Tripoli, thousands took to the streets to chants of “We want the lights to work”.

Some brandished the green flags of the former Kadhafi regime.

Calm appeared to have returned to Tobruk on Saturday, though there were calls on social media for more protests in the evening.

UN Secretary-General Antonio Guterres called on “all actors to refrain from any actions that could undermine stability” and urged them “to come together to overcome the continued political deadlock”, spokesman Stephane Dujarric said in a statement.


UN-mediated talks in Geneva this week aimed at breaking the stalemate between rival Libyan institutions failed to resolve key differences.

‘Extremely painful’ year

Presidential and parliamentary elections, originally set for December last year, were meant to cap a UN-led peace process following the end of the last major round of violence in 2020.

But voting never took place due to several contentious candidacies and deep disagreements over the polls’ legal basis between the rival power centres in east and west.

In Tripoli on Friday, hundreds came out to demand elections, fresh political leadership and an end to the chronic power cuts.

The sudden eruption of unrest appeared to be spreading to other areas of the country, with Libyan media showing images of protesters in the oasis city of Sebha, deep in the Sahara desert, torching an official building.

A local journalist said protesters in Libya’s third city Misrata were blocking roads after setting fire to a municipal building on Friday night.

After dark, protesters also gathered at several points in Tripoli, shutting down some roads and burning tyres, according to images broadcast by local media.

Interim prime minister Abdulhamid Dbeibah leads a Tripoli-based administration while former interior minister Fathi Bashagha draws support from the Tobruk-based House of Representatives and eastern military strongman Khalifa Haftar.

Haftar’s forces said Saturday that they “support the citizens’ demands” but called for protesters to “preserve public property”.


Libya expert Jalel Harchaoui told AFP that “for more than a year, the overwhelming majority of diplomatic and mediation efforts around Libya have been monopolised by the idea of elections, which won’t happen for at least two years, given the failure of the Geneva negotiations.”

This year “has been extremely painful for Libyans” because the country “imports almost all its food and the Ukraine war has hit consumer prices”, Harchaoui said.

‘Fragile situation’

Libya’s energy sector, which during the Kadhafi era financed a generous welfare state, has also fallen victim to political divisions, with a wave of forced closures of oil facilities since April.

Supporters of the eastern-based administration have shut off the oil taps as leverage in their efforts to secure a transfer of power to Bashagha, whose attempt to take up office in Tripoli in May ended in a swift withdrawal.

“There is kleptocracy and systematic corruption in the east as in the west, as the fancy cars and villas of the elite constantly remind the public,” Harchaoui said, accusing militias from both camps of carrying out “massive” fuel trafficking.






The European Union’s envoy to Libya, Jose Sabadell, said Friday’s events “confirm people want change through elections”.

But he urged peaceful protests, adding that “special restraint is necessary given the fragile situation”.

US ambassador to Libya Richard Norland said that “no single political entity enjoys legitimate control across the entire country and any effort to impose a unilateral solution will result in violence”.

He urged Libya’s “political leaders across the spectrum and their foreign backers to seize the moment to restore the confidence of their citizens in the country’s future”.

German town united by 400-year-old theatre tradition

Jesus
Jewish preacher and religious leader, central figure of Christianity


Walk around the German Alpine village of Oberammergau, and the chances are you'll run into Jesus or one of his 12 disciples.

Of the 5,500 people living there, 1,400 -- aged from three months to 85 -- are participating this year in the once-a-decade staging of an elaborate "Passion Play" depicting the death and resurrection of Jesus Christ.

Dating back to 1634, the tradition has persisted through four centuries of wars, religious turmoil and pandemics -- including the most recent Covid-19 crisis which caused the show to be postponed by two years.

"I think we're a bit stubborn," says Frederic Mayet, 42, when asked how the village has managed to hold on to the tradition.


Mayet, who is playing Jesus for the second time this year, says the Passion Play has become a big part of the town's identity.

The only prerequisite for taking part in the five-hour show, whether as an actor, chorister or backstage assistant, is that you were born in Oberammergau or have lived here for at least 20 years.

"I remember that we talked about it in kindergarten. I didn't really know what it was about, but of course I wanted to take part," says Cengiz Gorur, 22, who is playing Judas.
- 'Hidden talent' -

The tradition, which dates back to the Thirty Years' War, was born from a belief that staging the play would help keep the town safe from disease.

Legend has it that, after the first performance, the plague disappeared from the town.


In the picturesque Alpine village, Jesus and his disciples are everywhere -- from paintings on the the facades of old houses to carved wooden figures in shop windows.

You also can't help feeling that there is a higher-than-average quota of men with long hair and beards wandering the streets.

An intricate image of Jesus graces the stage of the open-air Passion Play theatre, where the latest edition of the show is being held from mid-May to October 2.

"What has always fascinated me is the quality of the relationship between all the participants, young and old. It's a beautiful community, a sort of 'Passion' family," says Walter Lang, 83.


He's just sad that his wife, who died in February, will not be among the participants this year.

"My parents met at a Passion Play, and I also met my future wife at one," says Andreas Roedl, village mayor and choir member.

Gorur, who has Turkish roots, was spotted in 2016 by Christian Stueckl, the head of the Munich People's Theatre who will direct the play for the fourth time this year.

"I didn't really know what to do with my life. I probably would have ended up selling cars, the typical story," he laughs.

Now, he's due to start studying drama in Munich this autumn.

"I've discovered my hidden talent," he says.
- Violence, poverty and sickness -

Stueckl "has done a lot for the reputation of the show, which he has revolutionised" over the past 40 years, according to Barbara Schuster, 35, a human resources manager who is playing Mary Magdalene.

"Going to the Passion Play used to be like going to mass. Now it's a real theatrical show," she says.


In the 1980s, Stueckl cut all the parts of the text that accused the Jews of being responsible for the crucifixion of Jesus, freeing the play from anti-Semitic connotations.

"Hitler had used the Passion Play for his propaganda," Schuster points out.

The play's themes of violence, poverty and sickness are reflected in today's world through the war in Ukraine and the Covid-19 pandemic, says Mayet, the actor playing Jesus.

"Apparently we have the same problems as 2,000 years ago," he says.

For 83-year-old Lang, who is playing a peasant this year, the "Hallelujah" after Christ has risen for the final time in October will be a particularly moving moment.

"Because we don't know if we'll be there again next time," he says, his eyes filling with tears.

Africa celebrates the return of Benin Bronzes, but questions remain

Across Africa, many are excited about Germany’s decision to return more than 1,000 Benin Bronzes to Nigeria. But there are calls for monetary compensation, too.

Artifact displayed in French museums, like this one, are also set to go back to Nigeria.

"This is perhaps the most significant agreement signed by a European nation with Nigeria with regards to cultural diplomacy," Yusuf Tuggar, Nigerian Ambassador to Germany, told DW after the agreement to return more than 1,000 Benin Bronze artifacts was signed on Friday. "It is a very significant achievement, a very significant milestone and we hope that it will lead to the return of not just the Benin Bronzes, but other stolen cultural properties from other countries as well."

In all, German museums hold more than 1,130 of the artifacts. They're spread across the Linden Museum in Stuttgart, the Berlin Humboldt Forum, the Cologne Rautenstrauch-Joest Museum, the Hamburg Museum for World Cultures and the State Ethnographic Collections of Saxony.

The importance of the decision to return the Benin Bronzes is underscored by the leader of the Bana people in Cameroon, Fon Sikam Happi V.

"It's a very good thing. This will allow Africa to come to terms with its past and reclaim these objects that would never have left Africa" if colonizers hadn't taken them, Fon Happi told DW. 

The valuable artifacts were stolen from the former Kingdom of Benin by the British when they sacked Benin City in 1897. The royal palace was razed to the ground, and Benin City, in what is now the southern Nigerian state of Edo, was almost destroyed. 

For many residents of Edo the news of the return couldn't have come at a better time.

"We are really happy about the news of the return of the Benin artifacts," Friday Osaro told DW. "Our heritage and assets that were stolen years back are being returned to the rightful owner, Benin Kingdom. We are really happy."

Lancelot Imansuen, a restitution activist, believes this decision will inspire creatives. "As an artist, as an Edo man, as a creative, I feel very elated by this move by the German government to return these artworks," he told DW. 

Across Nigeria, many see this as an opportunity to learn their history.

"This is like physical history for us. Everyone today can see this and know that our people had history and they were civilized to an extent because all these artifacts are not toys, they tell a story", Samuel Marv, a history graduate and user interface designer, said in an interview with DW. 

Pieces like this lion displayed in Cologne are among the artifacts set to be returned to Nigeria

For some, repatriation is not enough

Although there is excitement about the return of cultural artifacts to Africa, there are still questions surrounding the payment of compensation.

"Beyond the restitution of objects that have been stolen and exhibited in European museums, compensation must be paid. This would help Africa build proper museums to house these artifacts", Fon Happi added. 

Ify James, an independent contractor, told DW, "I think that the return of the Benin Bronzes should come with huge compensation, because it made them tons of money while they had them."

The agitation is particularly strong on Facebook. Justin Curtis, a user from Liberia, commented on a DW Africa video about the bronzes that "the healing process should be extended further to paying for what was done to Africa. This is a new way of seeing Africans as partners to a global solution to the many challenges we all face as a people".

Harry Koffi, another user on DW Africa's Facebook page added: "They must also return all monies they accrued from the museums that housed these artifacts." 

And while it is unlikely that Germany will pay any monetary compensation, German Foreign Minister Annalena Baerbock said during the official official ceremony on Friday that the country is "assisting Nigeria in establishing a new museum in Benin City, which will also display Benin Bronzes in the future." 

Benin Bronzes open up the conversation on African art

Other African countries are taking a cue from Friday's event, demanding that other artifacts be returned too. Togo, which was a German colony until 1914, says it will soon make a formal request for its art to be returned.

"There are teacher-researchers who are in German galleries and museums, identifying cultural property from Togo," Kossi Gbenyo Lamadokou, Togo's Minister of Culture and Tourism, told DW. "At the end of the identification of items in Germany and France, we will be able to say which of the items need to be repatriated." 

Lamadokou explained that not all African art in European museums was illicitly taken, and that Togo is specifically targeting stolen art


These Benin bronze artifacts and more than 1,000 others will soon return to their rightful home

In Tanzania, there is a growing debate over the return of the dinosaur ‘Brachiosaurus brancai' bones recovered by German paleontologists in 1909. The dinosaur bones were excavated from more than 100 sites in Tendaguru in southern Tanzania. Today, the dinosaur skeleton is the star exhibit at Berlin's natural history museum.

"The dinosaur fossil is important in matters of research in the area of archaeology and paleontology so if we are to receive it, we must also make sure that we have the human resources to retain it ― not only for the benefit of Tanzania, but also for the world", Tanzania's ambassador to Germany Abdallah Possy told DW.

Abdallah Possy explained that the East African nation has been in negotiations with Germany over the return of the dinosaur fossils. 

Germany returns Benin Bronzes to Nigeria

After a century of restitution claims, Germany is transferring ownership of 1,130 bronzes to Nigeria. A groundbreaking step in the return of looted art.

"It's a historic moment for us, for our two countries, that we are now signing an agreement for the return of the Benin Bronzes," Abba Isa Tijani, director of Nigeria's National Commission for Museums and Monuments (NCMM), told DW ahead of the ceremony on Friday.

The Nigerian commission has played a key role in drafting the restitution agreement signed in Berlin on July 1 by Germany's Foreign Minister Annalena Baerbock, Commissioner for Culture and the Media Claudia Roth, Nigeria's Minister of Culture Lai Mohammed and Minister of State for Foreign Affairs Zubairo Dada. "I like to express my gratitude to the trailblazing German government as the first European country in history to ever enter into a formal agreement to return all properties of the colonial past to their rightful owners. You have set the standards of what reconciliation should look like. It is my hope that other European countries who still posess such artifacts of ours will enter into your footsteps", Dada said.

The contract officially transfers ownership of the Benin Bronzes held by German museum collections to Nigeria, with immediate effect. "This is the known single largest repatriation of artifacts anywhere in the world. The president, government and people of Nigeria and especially the Oba of Benin, Oba Ewuare II are very happy and grateful to the federal government of Germany for making it possible", said Lai Mohammed.

Five German museums involved in restitution

In all, there are more than 1,130 artifacts from the Linden Museum in Stuttgart, the Berlin Humboldt Forum, the Cologne Rautenstrauch-Joest Museum, the Hamburg Museum for World Cultures and the State Ethnographic Collections of Saxony.

The valuable artifacts — sculptures and reliefs made of bronze and brass, as well as works made of ivory, coral and wood — were stolen from the former Kingdom of Benin by the British in a brutal punitive expedition in 1897. The royal palace from pre-colonial times was razed to the ground, and Benin City, in what is now northern Nigeria, was almost completely destroyed.

Admiral Sir Harry Rawson (center) led the punitive expedition

At the beginning of the 20th century, many of the stolen works of art were auctioned in London, with Germany securing the second-largest collection in the world.

The former Kingdom of Benin tried once to reclaim the bronzes 100 years ago — without success.

African intellectuals took up the fight again in the 1970s, but their demands fell on deaf ears in Europe.

It was French President Emmanuel Macron's visit to Burkina Faso in 2018 that marked a turning point: the French President announced that France would be returning its colonial art treasures and commissioned a report on how to achieve this.

The queen heads, such as the one seen in this picture, are particularly impressive

The report made waves in Germany. For Nanette Snoep, the fact that Nigeria and Germany are now coming to an agreement after protracted negotiations means that "history is now really being written."

"If the return and transfer of ownership of the Benin Bronzes succeeds now, then that really is the beginning of the decolonization of the so-called ethnographic bronzes museums," Snoep, who is the head of the Rautenstrauch-Joest-Museum, told DW. "This transfer of ownership is incredibly important, almost more important than the physical return."

From now on, Nigeria will decide how to deal with these objects and also how to talk about them: "It's about returning history and it's about a new narration of history," she added.

Icons of looted art

Nanette Snoep has been an advocate of restitution for nearly two decades

Every major museum in the Global North with collections from the Global South has at least one Benin Bronze: "These are the Warhols, these are the Rembrandts, the Dürers of the so-called ethnographic museums," said Snoep.

The fact that these "icons" of looted art are now being returned clears the way for "a new ethic in the field of international cooperation."

"It's about finally giving space to talk about colonial trauma, about broken or shattered memories."

However, a specific date for the "physical return" of the Benin Bronzes has not yet been set: "It won't happen overnight," said the director of Nigeria's National Commission of Museums and Monuments, Abba Isa Tijani. Transport, packaging, insurance, preservation and many other technical aspects have to be regulated first, he explained.

The bronzes are to be exhibited in various state institutions and museums, in galleries and in the rebuilt royal palace, which is to be inhabited by descendants of the once expelled king of Benin City.

The Edo Museum of West African Art (EMOWAA), originally planned for the Benin Bronzes, is still under construction, and it is unclear when it will be completed, explained Tijani.

In the Kingdom of Benin, the king was traditionally called 'Oba'

In Nigeria and especially in Benin City, the anticipation couldn't be greater: "We are really happy with the return of Benin artifacts. It means a lot. Our heritage, our cultural assets that have been stolen years ago, have been returned to their rightful owner, the Kingdom of Benin," said Friday Osaro, a resident of the former royal city.

Godwin Obaseki, governor of the state of Edo, where the former kingdom is now located, agrees: "The idea of ​​bringing these items home is not only important to our identity; they are a part of us. We can have them here and the world can come to us and see what we have created."

Some Benin Bronzes to remain on loan in Germany

Not all Benin Bronzes will return to Nigeria; some will remain in Germany on loan.

Abba Isa Tijani, director of Nigeria's National Commission of Museums and Monuments: 'Partnership is key'

Joint exhibitions with museums around the world are also planned. Tijani aims to focus on partnerships with museums as global institutions. "We don't want it to be just a return," he said.

The Nigerian commission is seeking to involve the large African diaspora in Europe: "When these objects go back to Nigeria, we are talking about a period of over 100 years that these objects have been outside the country," said Tijani. He believes that it is important to keep telling the stories of the journey of these objects, and of the communities and countries where they spent the past century.

Not only Germany is beginning to restitute cultural assets from colonial times. Most recently, the Glasgow Museum in Scotland returned 19 artifacts to Nigeria. The Smithsonian in the United States has restituted 29 pieces, and the National Gallery of Art in Washington has also agreed to repatriate objects from its collections.

Can heat pumps be the answer to higher energy costs?

As the price for oil and gas explodes in Europe, heat pumps could be a meaningful alternative. In Germany, lavish state subsidies are making the idea even more attractive for single-family homes.

There is a huge backlog for heat pumps because of supply chain issues and a lack of qualified technicians

With blistering summer temperature around much of Europe, it may be hard to convince people to think about heat pumps. But a push for more renewable energy plus the ongoing war in Ukraine and the curtailing of Russian gas and oil means there has hardly been a more pressing time.

A heat pump is a system that moves around thermal energy. There are a number of different types of devices based on what they use, including exhaust air, ground and water.

Ground-source heat pump equipment taps into the nearly constant temperature below the soil's surface. These geothermal heat pumps draw heat into a building in winter and remove warm air in summer, acting like an air-conditioner. This type of system uses a network of water-filled pipes that are either laid horizontally a few feet underground or pipes drilled vertically much deeper into the Earth's core.

Advocates say the systems can be used nearly anywhere and are cheaper to run than other heating and air-conditioning systems like boilers, furnaces and electric radiators. As energy costs skyrocket they are a way to access energy locally. Most important for many customers, heat pumps run on electricity and not gas or oil.

Installing a heat pump system can be costly, and the technology is often not suitable for old buildings

Heat pumps made in Germany

The heating and air-conditioning manufacturer Viessmann is showing the way. It is one of the market leaders in Germany. At the beginning of May when the company presented its annual earnings report, it announced that it would €1 billion ($1.05 billion) more in the production of heat pumps.

The company, which has 13,000 employees worldwide, recorded a 41% increase in sales in the heat pump sector in the past financial year, while total sales grew by just 21% to €3.4 billion.

These figures are a reflection of a swing toward electric heat pump technology. Not least because of large subsidies from the federal government to support the technology. Originally these subsidies were designed to reduce emissions of climate-damaging CO2. Now increasing energy costs have put these incentives in the national spotlight.

The initial outlay for heat pumps

Heat pumps are significantly more expensive than gas or oil heaters because their technology and design are more complex. Installation is also more complex and takes longer. Many components are located outside of buildings. The buildings themselves must be well insulated. Underfloor heating systems or extra-large radiators make a heat pump more efficient.

"In almost all cases, the conversion goes hand in hand with structural changes and often with a more energy-efficient renovation of the entire building," Thomas Auer, a professor of building technology and climate-friendly construction at the Technical University of Munich, told DW.

Heat pump system make the most sense for new-builds, although most do not look as nice as this one

The necessary investments can quickly run into the tens of thousands of euros. The state covers up to 35% of the installation costs in old buildings, and 45% if an oil burner is replaced. Most of the costs for a professional energy check are also reimbursed.

With such incentives in place it is no mystery why demand for heat pumps is growing. This has led to long wait times for an energy consultation or for workers to come and install a system. The sector, like many others, is facing a labor shortage, supply chain problems and sudden price hikes.

The war in Ukraine is making oil and gas unpalatable

The Russian war in Ukraine and the price of fossil fuels is another reason for increased pressure to move away from oil and gas for heating. But can electric-powered heat pumps solve acute energy problems?

"There is a very simple answer: Heat pumps can completely replace today's heating technologies, when you take into consideration hybrid heat pumps that combine gas and electricity," according to Thomas Nowak from the Brussels-based European Heat Pump Association, which says it represents the majority of the European heat pump industry.

Heat pumps are one of the key building blocks for the energy transition and for making the building sector climate-neutral, Christian Stolte from the German Energy Agency (dena) told DW. "Heat pumps use renewable energy and can generate three to four units of heat from one unit of electricity," he said.

For many older buildings heat pumps are not usually worth the big investment

Taking the long view and quickening the pace

Of the many million heating devices in German buildings, just over a million are heat pumps compared with more than 19 million gas and oil systems. To meet current climate targets, 4.5-6 million heat pumps would be needed by 2030. The German government has set a goal of 6 million. That is indeed a tall order. In the past 10 years, only 880,000 heat pumps were installed in the country according to the federal statistics agency Statista.

"In 2021, 154,000 heat pumps were installed. That is at least 28% more than in the previous year. This pace must pick up," said Stolte. Still even the massive increase in the number of heat pumps will not be able to make up for the high proportion of gas and oil heating in buildings in the short term.

Energy expert Manuel Frondel from the Essen-based RWI-Leibniz Institute for Economic Research agrees. "In the short term, heat pumps are not a solution to making us less dependent on Russian gas and oil," he told DW.

In new construction, heat pumps are the most frequently used heating technology in Germany, well ahead of oil or natural gas heating systems. But new buildings represent only a small part of the country's approximately 20 million residential buildings. In older buildings, retrofitting heat pumps is an expensive solution, both in terms of initial investment and operating costs.

Currently, most buildings in Germany are heated using oil or gas

Even the massive government subsidies do not change that, according to Frondel, who heads the Environment and Resources department at RWI. He calculates that if 2 million heat pumps were subsidized for older buildings by 2024, it would cost the government at least €42 billion. "Such a sum cannot be justified by anything, especially not with climate protection arguments," he said.

Keeping out the cold with better insulation

To make matters worse, there is no guarantee that homes with subpar insulation will actually get sufficient heat from a heat pump. "Experienced heating engineers therefore advise against installing a heat pump in poorly insulated houses, and rightly so," said Frondel. This lack of efficiency means buildings may have to keep their traditional heating system in addition to any new heat pump.

"For every single household, switching to a heat pump is, of course, a big step forward in terms of independence from natural gas," Jens Schubert, an energy expert at the German Environment Agency (UBA), told DW.

Using more renewable energies to heat and implementing more measures to make buildings energy-efficient should be encouraged now even though they will only have an effect in the medium term, he argues. Until then, customers will have to wait in line to get their heating systems updated and can expect a big installation bill afterward.

James Webb Space Telescope: Just a huge thermal camera

Astronomers have long used infrared technology — the same as in thermal imaging — to see deep space. Our biggest space telescope takes it to another level.

Scientists are abuzz with anticipation for the first full-color images from the James Webb Space Telescope, the biggest and most powerful infrared space-based telescope, which will be revealed in July.

"[The images] are sure to deliver a long-awaited 'wow' for astronomers and the public," said Klaus Pontoppidan, an astronomer at the Space Telescope Science Institute in the US.

It took more than two decades to develop the James Webb Space Telescope, at a cost of about $10 billion (€9.48 billion), and it's hoped that these first images will go some way to justify all the work, time and money.

A joint project between NASA, the American space agency, and the European and Canadian space agencies, the James Webb Space Telescope was launched in December 2021.

It uses infrared to allow scientists to see deep into space. They want to see distant galaxies and stars and understand how they have formed.

They also hope the telescope will allow them to learn more about exoplanets — planets that orbit stars than our own sun — and to look for signs of life.

What is infrared?

As with visible light, the kind we can see with our eyes, infrared is a form of electromagnetic radiation.

Electromagnetic radiation comes in different wavelengths that lie on a spectrum, which starts with radio at one end and includes microwave, infrared, visible light, ultraviolet, X-ray and gamma ray.

Infrared is itself a large part of the electromagnetic spectrum and is divided into near-infrared, mid-infrared and far-infrared.

If you've seen movies like "Predator," the documentary series "Planet Earth" or the performance by Thirty Seconds to Mars at the 2017 MTV Video Music Awards, you'll be familiar with infrared light and some of its uses.

All of the above examples used thermal cameras, which capture infrared light.

Thermal cameras are also used at airports to measure peoples' body temperature, which increases when you get a fever, for example from an infection with SARS-CoV-2.

Some snakes like vipers, pythons and boas have special "pit" organs that can detect infrared radiation — or body heat — from their prey as well.

How do infrared thermal cameras work?

Anything that is above absolute zero (-273.15 degrees Celsius / -459.67 degrees Fahrenheit), whether living or inanimate, emits infrared radiation — that includes you and the chair you're sitting on.

Even if we can't see the object with our eyes, it will emit heat radiation. We can detect that radiation with infrared and then convert that data into an image, using different colors to illustrate the intensity of the infrared radiation. And that creates a contour with detailed outlines of the object.

The James Webb Space Telescope will deliver the sharpest images of deep space to date

That's similar to how infrared telescopes like the James Webb Space Telescope create images from space.

Why use infrared on the James Webb Space Telescope?

Astronomers need infrared to be able to see the earliest stars and galaxies.

Infrared allows us to see through dust clouds that would otherwise block our view.

Dust clouds are where stars and planets are born, and being able to see through them will help us better understand how those stars and planets form.

The James Webb Space Telescope has a massive mirror to capture light from distant stars and planets.

The mirror is six times larger than the one used on its  predecessor, the Hubble Space Telescope. The James Webb Space Telescope should be able to see objects that are 10 to 100 times fainter than what Hubble could see, and take much sharper and detailed images in infrared than any previous telescope of its kind.

A new era in infrared

Infrared was discovered in 1800 by German-born British astronomer William Herschel, one of the main astronomers behind the discovery of Uranus.

Herschel used a prism and a thermometer to measure how different colors of light influenced temperature and noticed the biggest increase in temperature was in a region that became known as infrared.

The James Webb Space Telescope launched in December from Europe's spaceport in French Guiana

There have been many more discoveries and technological improvements since then, including the first detection of infrared radiation from the moon on 1856.

In 1878 came the invention of the bolometer, an infrared measuring device, that was used in an updated form on the Herschel Space Observatory until 2013.

Infrared detectors continue to improve in sensitivity and accuracy, allowing scientists to detect infrared light from planets like Jupiter and Saturn.

The James Webb Space Telescope will now add to this rich history by looking further back in time than ever before, and with unprecedented detail.

If we're lucky, it will reveal what the universe looked like just a few hundred million years after the Big Bang.

How Germany and the EU combat child abuse

The perpetrators are babysitters, neighbors, teachers, or fathers. International leaders have pledged to put an end to sexual abuse of children — a global phenomenon with Europe as a hotspot.

Everybody knows victims and perpetrators of child sexual abuse, says Germany's Commissioner

"We commit to strengthening our fight against human trafficking and our efforts to prevent and combat sexual abuse and sexual exploitation of children worldwide, both online and offline," the G7 leaders pledged in their final declaration of the summit in Germany.

Wibke Müller of the victims' group Brave Movement called this a historic step. "When I was a child, no one protected me from sexualized violence," she said. "Today, for the first time, G7 leaders have collectively committed to being the protectors that all children deserve."

Germany has recorded a rise in child sexual abuse cases. Yet another came to light in Wermelskirchen, a town outside the western city of Cologne, just recently, when a 44-year-old male babysitter is believed to have sexually abused 12 babies, toddlers, and children with disabilities. His youngest victim seems to have been only one month old.

The latest major case that came to light involved a male babysitter

Police caught him at his computer and arrested him. He is suspected of trading child abuse images and videos with more than 70 other people. The investigation is still ongoing.

Police in the state of North Rhine-Westphalia have uncovered several major abuse networks involving multiple perpetrators and victims. 

Kerstin Claus, head of the German government's new Independent Commission for Child Sexual Abuse, told DW that "the Wermelskirchen case illustrates the fact that, via the spread of digital media, acts of violence of the most monstrous kind are becoming more visible, although they existed before the Darknet emerged."

The difference is that "today we can prove that violence occurred," she said.

A race against time

Finding victims and perpetrators is the job of the Cologne police's cybercrime task force, headed by prosecutor Markus Hartmann, who has launched more than 9,300 cases against nearly 9,900 suspects in the past two years.

Many of the tip-offs about sexualized violence online come from the United States' National Center for Missing and Exploited Children (NCMEC). 

A prerequisite for prosecution is that perpetrators are identified quickly, but Hartmann said that tips often reach investigators too long after the fact for IP addresses to be traced. For that reason, Federal Interior Minister Nancy Faeser has thrown her support behind a measure that would require internet providers to hold onto this information for longer.

Police statistics show a steady increase in the number of child sexual abuse cases uncovered every year

Mountains of data

Commissioner Claus stresses that victims are "often at the mercy of their tormentors for months and years," sometimes in their own family or immediate environment. The number of unreported cases is likely many times higher than the statistics show, she says, calling it a "scandal" how much is still unknown.

The victims who advise commissioner Claus have pointed out that sexualized violence "remains one of the safest crimes for perpetrators," and that two-thirds of investigative proceedings are dropped, especially if they come down to the victim's word against the perpetrator's word.

More than 30 terabytes of data were seized in Wermelskirchen, and the NRW cybercrime unit uses artificial intelligence tools that can identify 90% of child abuse images, Hartmann says. This allows investigators to gain a quick overview of large amounts of data to figure out whether a child somewhere is currently being abused.

In the end, however, humans have to assess images and videos, so there are calls for more personnel and equipment.

International cooperation needed

Statistics show that Europe is a hub for abuse imagery. So Commissioner Claus welcomes the European Commission's plans for an EU center to complement national law enforcement agencies and support victims in their right to delete depictions of abuse.

Markus Hartmann would also like to see more international cooperation. There has already been some success in working with specially-trained partners in the Baltic states, Hartmann said. "Sometimes cooperation across European borders has been even faster than across [German] state borders," he remarks.

Awareness has risen over the past years, says Commissioner Claus, "but many people still don't want to admit that it affects children around them. "We all know victims, so we also know perpetrators," she says. 

Experts believe that in every school class, one or two children are affected by abuse.

Early childhood trauma — shorter life-expectancy

Psychologist Matthias Franz has worked with victims of child abuse. He explains that even infants store memories of events that caused them fear and pain in a special part of their brain, the amygdala. So early experiences of abuse or violence can be written into pre-linguistic memory.

"If I experienced bad things as a child, the memories might rise up again 40 years later, say, if my boss at work gives me a look that reminds me of the way my father looked before he beat me up," Franz explains. "Stress hormones are then released, which can trigger a panic attack so I may end up in hospital with a suspected heart attack." Often such patients, says Franz, are just sent home again. If they are lucky, a doctor may diagnose a panic attack and suggest psychotherapy.

"We know from long-term studies of severely abused children that they are much more likely to develop psychosomatic or addictive disorders later on," Franz says. "There are studies that show that children with severe abuse experiences can have a reduced life expectancy of up to 20 years."

The psychologist says it should be easier for adult victims to get diagnosed and find easy access to therapy.

Research on perpetrators

When perpetrators are unmasked, their colleagues and neighbors often remark on how inconspicuous they seemed.

Psychologist Matthias Franz explains that many perpetrators lack empathy and seek power over weaker people. "It gives some people…an intoxicating feeling of omnipotence to leave all ethical boundaries behind," he says.

The dissolution of boundaries on the internet acts as an accelerant: Perpetrators reinforce each other's belief in the legitimacy of their actions. "We urgently need more research on this," says Franz. "How do perpetrators get to be that way? Is it treatable?"

Primary school children during class

Experts believe that in every school class, one or two children are affected by abuse.

Prevention and protection

Hartmann's cybercrime task force also conducts public information campaigns to warn potential perpetrators that they risk getting caught. Investigators have also produced teaching materials to combat what is known as grooming, when a perpetrator first establishes contact with a child over a long period in order to make them more amenable to abuse.

Educating children, teachers, and parents is important, says Claus, but she also calls for binding rules for digital spaces in which children largely move alone: protective default settings, low-threshold offers of help, stricter age restrictions, and moderation of websites.

And she wants to launch a campaign later this year to ensure people know exactly where to find help in protecting children from abuse, just like they know how to trigger a fire alarm.
